An easy way is to do it, if you get confused by multiplying fractions, is by turning the fractions into decimals. Since you are trying to find N you want to multiply the 1/5 by the 1/3.
1/5 = 0.2
1/3 = 0.33333333333333333333333333333333
if you multiply those you get 0.06666666666666666666666666666667 which when put into a fraction it equals 1/15
but if you don't want to do that just try to remember that you want to get by itself. and when multiplying fractions in this situation the bottom numbers only matter.. so 5 x 3 = 15 1/15
would you like me to put it in a document to show you?
Hello!
To find cosine, use the formula cos = adjacent / hypotenuse.
According to angle B, adjacent of angle B is side A, and the hypotenuse is side c because the hypotenuse is always opposite the right angle.
Therefore, the cosine of angle B is a/c.
Answer: The building would be 11 inches wide
Step-by-step explanation:
Answer:
-0.5 and negative one-half
-1/50 and -0.02
Step-by-step explanation:
-0.5 can be rewritten as -5/10. This can be simplified to -1/2 which is the same as negative one-half.
7/10 isn't equivalent to 11/20. If you multiply 7/10 by 2/2 to get the denominator of 20, it will become 14/20 not 11/20.
-1/50 in decimal form is -0.02 so -1/50 and -0.02 are equivalent.
0.15 and 1/5 aren't equivalent because 1/5 in decimal form is is 0.2, not 0.15.
Answer:
they are acute
and are also equivalent
that's the relation in the 2 angles
